The disks J and J 2 are of a diameter.

To all whom it may concern:

Be it known that I, S'rANLEr W. NronoL- SON, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio,.have invented certain new and useful Improvements in Window- Control Mechanisms, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention rel-ates to motor vehicles.

' The invention consists in a novel mechanism for actuating apivotal control arm for v a sliding window and in a locking means for I i enumerated, I is a rectangular plate secured 1 maintaining said arm stationary coaxial relation in the improved mechanism;

Figure 7 is a horizontal sectional view of the parts assembled upon the lockmg plate;

Figure 8 is a cross section view of the same taken on line 8-8 of Figure 7. v

In these views't-he reference character A designates a window opening in the upper portion of an automobile or other vehicle and B is a vertically slidable glass plateforming a closure for the opening A and adapted in'lowered position to enter a chamber C formed below the opening A. D is a control arm .for the plate B, pivotally mounted at D, and carrying at its free 'end a roller E bearing against the lower edge of the plate B. The arm D is formed at its pivotal extremity with a segmental gear H which meshes with a pinion I upon a stub shaft I adapted to be driven by a handle I, accessible as is common practice interiorly of the vehicle.

Describing now the mounting for the parts within thechamber C and having a circular opening I mar 'nally' formed with gear teeth I. J, J, z and. J are disks for operatively connecting the stub shaft I to the handle member I. Thedisk J is disposed in the plane of the plate 1' within the openwindow control mechanism, and more particularlyto devices. for raising and lowering the w ndows of ing I. somewhat greater than that of the) disk J and are arranged coaxially with the latter at opposite sides of the plate I, the three said disks being rigidly connected for unitary rotation by rivets K. The'stub shaft Iprojects integrally from the disk J in one direc tion and a pin L projects in the opposite direction coaxia'lly withsaid shaft passing free through an opening Min the disk J The outer end mounting or the handle 1 the latter being integrally formed with a circular plate M and screws *N being extended through said plate into the disk J" to rigidly attach the ortion of the pin L provides a.

handle to said disk. N is a screw axially connecting the handle I and pin L, said I screw having a large head N for retaining "the handle rotatively on said pin. Thus it is seen that the handle I and disk J a are con nected in a unitary relation and are adapted i. to turn upon the pin L independently of the unit formed by the disks J, J, J

The disk J is formed with a radial slot 0 within which there is slidably mounted a latch bolt P havingat its outer end an integral tooth Q and acted upon by a coil spring R urging said bolt outwardly to engage said a tooth between any of the notches I with which said tooth may be registered. Said latch bolt carries a radially projecting pin.

S passing through a radial slot T in thefdisk J and entering an approximately triangular cam opening U in the disk .Considering now the operation of the described construction it is tobe understood that actuation of the handle I in either direction first retracts the bolt P and then establishes a drive to the-unit J, J, J 2 to swing the arm D up or down according to the'direction in which the handle. -I is turned.

Analyzing this result it will be seen that the disk J 8 turns as a unit with the handle I? owing to the connection established by the screws N. The pin S projectin into the cam' opening U provides for a'slig t lost motion between the unit formed b the disk J J, and J Normally the pin apex or outermost 'oi-nt of the slot ing to the outwar efiort exerted by the spring R. In takingup'the initial lost-m0:

enga es the I ti n, one or the other of, the inwardl di-"' verge nt edges of the cam opening upon the pin S (according to the direction of rotation of the handle? to eiiectretraction of latch bolt formed of stam ed sheet metal, of substantially the same thic ness as said pivot the bolt PL Thus by the time the lost mo-' tion is fully taken up the tooth I is disengaged from the notched edge I and continued rotation of the handle I? will drive the unit J J J 2 through said pin S and will communicate'the desired angular to the arm B.

It is to be observed that the invention demovement 'rives from a single spring the functions of normally projecting the bolt P and maintaininga neutral or intermediate position of "the handle as regards the lost motion movement of the latter.

It is further to be noted that'the relatively small pinion I acting upon the large segment H provides an exceedingly simple mechanism for'angularly adjusting the arm D with a very slight manual effort.

An important advantage derived from the described construction is the economy involved in use of sheet metal stampings for most of the elements'of' the mechanism, it-

member, the mounting plate being formed with a notched opening to receive the pivot member and the latter being radially slotted to mount the latch bolt, a spring urging the latch bolt. into engagement with the notched periphery of said opening, a drive member connected to said pivot member at one side of themounting plate, a driving member at the other side of the mounting a plate, having a lost motion connection to the pivot member for retracting said bolt.

'2. In a device of the character described, the combination with a disk shaped pivot member, of a bolt radially slidable in said inember', a mounting plate formed with an opening receiving said pivot member, said opening being peripherally notched for engagement by said bolt, a spring between said bolt and pivot member urging the bolt into engagement with the notched margin of said opening, a pair of disks of greater diameter than said pivot member at opposite sides of'said mounting plate, one of which pair is radially slotted, means rigidly connecting the said disk and pivot member, a

driven member connected to the other disk of said'pair, a pin upon said bolt projecting through saidslot, and a handle member having an opening formed with o posed bevelied edges engageable by said projecting 3. In a device of the character described the combination of a pivot member for a control arm, a bolt,radially slidable in said pivot member, a mounting for said pivotv member notched for engagement by said" bolt, a handle member for actuating said pivot-member having a lost motion connec-u tion' to the "pivot member for-initially retracting said bolt -upon actuation of the handle, and a single spring urging said bolt into normal projected position and also maintaining a normal neutral position of the handle with respect to the lost motion movement thereof.

4. In a device of the character described, the combination with a sheet metal plate having an opening therein with a notched margin, of a sheet metal .diskf fitted in said opening, a window control elemeritflsecurfld to said disk at one side of said plate, a latch member mounted" in said disk for engagement with the notched periphery of'said opening,'an actuating member in said control element carried by said disk at the-other sideof said plate, said actuating member having a lost motion drive connection with said disk, and means for effecting retraction of said latch member through the initial lost motion travel of said actuating member.
